This is dated August 1995. It's not bad - there's a fair amount of action, and the layout is good for the period - but I can understand why it wasn't used in the Master Levels. The staircase mentioned by the one of the previous reviewers is unintuitive (you have to press it), and a later secret with a megasphere seems inescapable. The cyber fight is a pushover, because you get five(!) invincibility spheres, two megaspheres, etc; the Master Levels were tough.
